that doesn't seem right at all. I can get a PS3 copy which has Silent Hill 2 and 3, and I didn't even think it was on the PC.

I advise the HD one. The second is a standalone game, while the 3rd is a sequel to the first, but still a good game on its own.
I don't know what Amazon you'e using but on AMazon, it's $25 used and $80 new.
